ABSTRACT:
A prosthesis for replacing the elbow joint includes a humeral component having a body portion defining a plurality of generally semi-circular distal bearing surfaces extending therefrom and a proximally extending intramedullary canal stem. An ulnar component has a body portion defining a convex posterior surface adapted to be received within a prepared semi-lunar notch of the ulna, a plurality of semi-circular grooves configured to matingly receive the distal bearing surfaces of the humeral component, and a distally extending intramedullary canal stem. The ulnar component further defines a laterally positioned capitulum process having a distal surface adapted to be abutted against by the head of the radius bone upon implantation. The humeral component defines an aperture and the ulnar component includes a hook-like member adapted to detachably and hingingly interconnect the components in a slipfit fashion.
